Respirator with Replaceable Filter POC

Respirator with replaceable filter POC. This is in no way meant to be used by anyone. It was built as a proof of concept. Hot glue was used to secure the filter to the inside of the respirator cover. The cover was then hot glued to the outside of the mask. Weather seal (used for windows and doors to seal drafts and found at most local hardware stores) was used to create a seal between the mask and the face. An elastic hair band was cut and sewn through the loop on each side. Size is measured from the center of the bridge of your nose to the bottom of your chin. XXS = 85, XS = 95mm, S = 105mm, M = 115mm, L = 125mm
